That is a pretty common sense answer that is the trade-off you want more air in your engine to produce more horsepower supposedly the obvious answer is yes it's going to let more debris in as well choose your poison.
Has the K&N been oiled? Also, doesn't the air pass through all those filter from the bottom to the top, not from the top to the bottom, as you had poured the sand/dust?
Just disconnect battery, wait 10 seconds and reconnect, start car, turn to lock both sides then back to center, turn car off then on again and it's cleared
Thanks so much for doing this. Really helps many of us make an informed decision, especially on something so expensive (shouldn't be) as an intake upgrade.
Pointless test ... wtf are u pissin about with iron dust for ... only result of this test is you've ruined a BMC/Sprint filter by pouring sand & iron dust in it u fool ... OEM pleated paper filter won't let any particles through (Fact)
Thank you for actually doing the leg work and showing us real time stats. Very informative. Thank you so much for this video. Everyone should watch this video!
I buy my Yamaha royal star venture used. It had 30,000 miles on it, and it had K & N stock replacement air filters, there are two air filters on these machines. I have a video on my RU-vid channel, Yamaha royal star venture major flaw is the title of it. In that video, I pointed out all the filth and dust inside my intake system. I was blaming that on loosefitting plumbing of the intake system to the carburetors. But it turned out to be the K and N Eric layers were leading all of that dirt in… I have another video pointing out what I would do if I were anyone watching the video that had KNN air filters in their machine. They may pass more air which they do in testing, but, they also let more than 10 times the dirt get in. A RU-vidr with a website called project farm prove that by sifting flour into a box with a vacuum below the box, pulling air through the filters in a comparison with a meter that measured particulates that go through the filters. The K and N oiled air filter was the one that passed the most air, and the most Particulates
As soon as I saw Mahle and Mann case closed for me I live by the outstanding quality and performance by Mann I am beyond shocked the people for real use a fram oil filter $1 from Walmart in these cars never in hell could I do that
